'When most readers go into a bookstore, they don't take a lot of notice of who publishes the book they're browsing through or looking for, they just want to buy the darn thing. They take even less notice of what imprint the book is published under. One thing that regular readers of series romance are much more aware of, however, is lines. They may not use this word. They're more likely to say, 'the ones with the purple covers', 'the Silhouette Special Edition', or 'the medical romances'.
